Just about everyone or their family uses public swimming facilities. The Council for the Model Aquatic Health Code (CMAHC) promotes health and safety at the nation's public swimming pools and hot tubs through use of the science-based guidance found in the Centers for Disease Control and Prevention’s (CDC's) Model Aquatic Health Code (MAHC), the only all-inclusive national model pool code. The CMAHC, a member-driven organization, is unique in that no other organization exists exclusively to advocate, evolve, innovate, promote implementation, organize research in support of, and advise CDC on needed updates to the MAHC.
